The outer shape of resin-cast body 3 is a blade shape.
Aluminium sheet 2 is identical with resin-cast body 3 shapes, and aluminium sheet 2 external dimensions are less than resin-cast body 3 external dimensions.
The manufacture craft of casting type LED light fixture, making step is:
(1) as required light fitting shape is processed mould;
The aluminium sheet 2 that (two) led light source 1 will be installed is installed on the dies cavity centre position;
(3) resin material is melted, and be cast in the mould;
(4) mould matched moulds, and wait for resin solidification;
(5) light fixture is promptly processed in the demoulding behind the resin solidification.
Above-mentioned dies cavity is a blade shape.
Said aluminium sheet 2 is identical with the dies cavity shape, and aluminium sheet 2 external dimensions are less than the dies cavity size.
The present invention places the LED lamp body among the casting mold cavity that comes in every shape that designs moulding; And the casting transparent resin as a whole so that resin and LED illuminator are frozen into, treat that resin solidification is sloughed mould after; Give the energising of the LED illuminator after solidifying, make whole light fixture entirely lighting.Give the corresponding pedestal of lamp holder dispensing then, pedestal connects aluminium sheet, promptly forms a light fixture that practicality is complete.Adopt this technology not only to be confined to above-mentioned blade type light fixture, can also process various moulding as required.The method can random flexibly producing comes in every shape, purposes is different light fixture.
LED light fixture of the present invention and conventional lamp relatively do not have the notion of conventional lamp fully, can't see seen lampshade and bulb usually, but the lamp holder entirely lighting of whole light fixture.Its advantage is following:
1, aesthetic design: outstanding world today's industrial design trend that embodies surmounts the conventional lamp method for designing.Adopting the airflow design theory of big curve, is the basis with the ergonomics, and whole stealthy design is brief generous.Any protrusion can't see in the outside, as: screw, switch etc.And conventional lamp can't be moulded the moulding that comes in every shape because of its intrinsic structure.
2, intelligent control: can use and send the pure soft white light of light; And control mode is more flexible; Can regulate brightness through modes such as touch, remote control, human body sensings, can realize that handset touch panel generally controls touch dimmer, perhaps according to ambient brightness intelligence adjustment light intensity automatically.And conventional lamp is difficult for realizing.
3, long-life design: can reach 30,000 hours service life.Common bulb has only hundreds of hour.
4, control simply, and the conventional lamp light modulation is difficult.
